Slide ruler: BMW M3 GTS takes on Austrian Alps
A charge to the roof of Europe requires a special kind of car. A car that makes the standard M3 look like a soft-edged fatso

That engine is a hell of a present, and much more than just breathed-on. This is a motorsport unit, with a race-spec block, and though its bore is the same as before, the stroke has been increased to 82mm. This, in turn, has increased the 4.0-litre V8's volume to 4,361cc, and there's an additional 30bhp (now 444bhp) and 29lb ft of torque. It now produces 325lb ft at 3,750rpm, 150 lower than before. On paper, it sounds like a car that should be more flexible about dishing up its potential than its surprisingly highly strung, high-revving brother. At 1,530kg, it's only 75kg lighter, but we'll give it the benefit.
